Re: Dimensions, 2D, 2.5D, 3D

3 records added to abbreviation table in database at

http://groups.yahoo.com/group/CCEDstore/database

2D 2 dimension x and y changes simultaneously, z constant
http://www.tancadem.com/TanCadem10.htm

2.5D 3 dimensional with limitation on z z constant during xy
move, then move to new z for another series of xy move
http://www.tancadem.com/TanCadem10.htm

3D Full 3 dimension xyz can move simultaneously
http://www.tancadem.com/TanCadem10.htm

This table/database is searchable

eg. To find meaning of TTY, under [Database Help] [This Table] type
in the abbreviation [TTY], enter
